Title: Balanced modulation unit
Inventor: OMATSU SHIGETOMO
IPC: H03C1/58
Filed: 1979-05-11
Abstract: PURPOSE:To enlarge a signal source impedance to prevent effectively the mutual interference between respective signal sources without leakage of the carrier wave, by inserting a carrier wave trap circuit in parallel with signal sources. CONSTITUTION:A carrier wave trap circuit which consists of coil L0 and capacitor C0 and resonates to the carrier wave is inserted in parallel with two different signal sources W1 and W2 of a balanced modulation unit. Therefore, since the impedance for the carrier wave frequency in the secondary side of transformer T1 becomes small even if the signal source impedances Z1 and Z2 are enlarged a little for the purpose of preventing the mutual interference of signal sources W1 and W2, carrier wave components are flowed into the balanced modulator sufficiently to perform a normal modulation operation, and the carrier wave is prevented from being overflowed as an output. Then, coils L1 and L2 inserted in series to signal sources W1 and W2 are provided for preventing the carrier wave trap circuit from being dumped by impedances Z1 and Z2.

Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To effectively calculate a filter coefficient of an IIR type periodic time change filter that realizes an impulse response of plural conventional IIR type time unchange filters approximated by an impulse response represented by a finite time. SOLUTION: In a general equation of a time change filter unit 1 of a coder TX, filter coefficients a(k), b(k) are changed as a period of P-times. Thus, the characteristics of the time change filter unit 1 is represented by P-sets of impulse response. In order to obtain the time change filter unit 1 with an equal characteristics as a conventional time change filter unit, the filter coefficients a(k), b(k) are decided to realize the impulse response of the conventional time change filter unit. Then a decoder Rx has an equal function as that of a conventional decoder and the time change filter unit 8 has different filter coefficients c(k), d(k) from those of the conventional time unchange filter.

Abstract: PURPOSE:To facilitate any change of the rotating speed of a blast shifting vane in such a way that movable blast shifting vane bodies are installed on the blast shifting vanes so as to change the force to be applied to the blast shifting vanes with forced air flow. CONSTITUTION:When blast shifting vanes 72 are rotated to this side since one of resilient pawl pieces 93, 94 contacts embossed flutes 89, 90, the rotation to this side is prevented. When the blast shifting vanes 72 are reversely rotated, since the other one of the resilient pawl pieces 93, 94 contacts the embossed flutes 89, 90, the rotation is prevented. Since the contact of the salient portions at the free ends of the resilient pawl pieces 93, 94 make those pieces 93, 94 to be bent so as to have the contact released, there is no necessity for retreat. In consequence, the blast shifting vanes 72 can be smoothly operated within a certain specified range, and rotating speeds of the blast shifting vanes can be changed.

IPC: H01L27/06
Filed: 1983-04-04
Abstract: PURPOSE:To obtain the semiconductor integrated circuit device having a J-FET from which a large output impedance can be led out without increasing the gate length by a method wherein the channel part under the gate region is projected out to the substrate side. CONSTITUTION:A thick oxide film 23 is formed at the part produced by removing a nitride film 22, and, together therewith, an N-well region 20 immediately under said oxide film 23 is pushed out by dipping effect. Thereby, the P-N junction surface of the bottom surface of the N-well 20 does not become flat, and accordingly a part projects out to the substrate side. In this manner, the N-well of the channel part immediately under the gate 24 of the J-FET is locally pushed in (pushed out to the substrate side) over the range slightly wider than the gate 24, thereby the effective channel length of the gate is increased without varying the gate region 24. Therefore, the output impedance increases without increasing the junction capacitance of the gate.

Title: Ground clearance regulating device for vehicle
Inventor: OKADA HIDEYUKI
IPC: B60G17/015
Filed: 1986-03-17
Abstract: PURPOSE:To simplify constitution and to prevent regulation of a ground clearance due to a temporary fluctuation, by a method wherein, when ground clearances detected by ground clearance sensors disposed on the diagonal line of a car body are opposite to each other, the action of a driver for actuating a ground clearance regulating body is prohibited. CONSTITUTION:Ground clearance sensors 42 and 43 are placed on a diagonal line. When a car body 1 is, for example, dived, the ground clearance sensor 42 on the front right side detects that a ground clearance is decreased to a value lower than a set value, and outputs a low ground clearance signal L and the ground clearance sensor 43 on the rear left side reversely outputs a high ground clearance signal H through signal processing circuits 47 and 48, respectively. Thus, an AND circuit 59 produces a high level, and an output from an OR circuit 60 also produces a high level. From an inverter 61, a prohibition signal of a low level is outputted, and a switch circuit 62 closes each exhaust valve and feed exhaust valves 25-29 to prohibit regulation of a ground clearance. This constitution enables prevention of regulation of a ground clearance due to temporary behavior of a car body.
